Yes, I believe they are equivalent because if you were to solve -1/4(10t-15) it would equal -2t+3
A=(a+b)*h*1/2=(20+8)*7*1/2=49 m2
V=A*H=49*2=98 m3
I think it has 2 pairs of parallel sides
$120 because the fencing of the patio would use up eight squares and each square in the picture is 3 meters so we would need 24 meters of fencing to cover up the entire patio. Since it cost $5 for one meter, 5*24 is $120.
